Sanitary silicone is specifically designed for use in areas where hygiene is a priority, such as bathrooms and kitchens. While it can be used in door frames, it may not provide the same level of durability and adhesion as regular silicone. It is always best to use the appropriate type of silicone for the specific application to ensure the best results. **

To sew silicone rubber bands without the machine's foot gliding over them, you can try using a non-stick presser foot or a Teflon-coated presser foot. These types of presser feet are designed to reduce friction and prevent sticking on difficult fabrics like silicone rubber. Additionally, you can try using a walking foot attachment on your sewing machine, which helps to feed the fabric evenly and prevent slippage. Finally, adjusting the presser foot pressure on your machine may also help to prevent the foot from gliding over the silicone rubber. **

Yes, silicone does stick to silicone. When two silicone surfaces come into contact, they tend to adhere to each other due to their similar chemical composition. This property makes silicone a popular material for creating airtight seals and bonding silicone-based products together. **

It is generally not recommended to apply new silicone on top of existing silicone. The new silicone may not adhere properly to the old silicone, leading to potential issues with adhesion and durability. It is best to remove the old silicone completely before applying a new layer to ensure a proper bond and a long-lasting seal. **

Yes, silicone can be applied on top of existing silicone. However, it is important to ensure that the existing silicone is clean and free of any dirt, dust, or residue before applying new silicone. Additionally, it is recommended to use a silicone primer to promote adhesion between the old and new silicone layers. This will help to create a strong bond and ensure a durable seal. **

To make silicone at home, you will need to mix together silicone oil and a catalyst. The most common silicone oil used for this purpose is dimethylpolysiloxane, which can be found online or at specialty stores. The catalyst, which initiates the curing process, is typically a mixture of tin and platinum compounds. Once you have the silicone oil and catalyst, you can mix them together in the proper proportions and allow the mixture to cure to form silicone. It's important to follow safety precautions and proper measurements when working with these chemicals. **

Silicone lenses are a type of contact lens made with a silicone-based material, which allows for increased oxygen permeability to the eye. This can help reduce the risk of eye infections and improve overall comfort. Silicone hydrogel lenses are a specific type of silicone lens that also includes hydrogel, a water-absorbing material that helps keep the lenses moist and comfortable for longer periods of time. These lenses are popular for their breathability and comfort, making them a popular choice for contact lens wearers. **

If you suspect that the frame counter of your analog camera is broken, there are a few ways to confirm this. First, try advancing the film and see if the counter moves accordingly. If it does not, then it is likely that the frame counter is broken. You can also try taking a few test shots and see if the frame counter accurately reflects the number of exposures taken. If the counter does not change or is inconsistent with the number of shots taken, then it is likely broken. Lastly, if you are still unsure, you can take your camera to a professional camera repair shop for a more thorough inspection. **
